Thanks for your question Finn! The answer depends on what you mean by change.
The government can change following a federal election depending on which team wins the majority (76 or more seats) in the House of Representatives. The Australian people decide who is to form government by electing representatives to the House.
There are many ways that Australian society may change over time. Governments may choose to respond to change by making laws. For example, when the internet arrived in Australia in 1989, the government needed to make new laws about how it should operate or be run.
